Claims28
Raney copper which is doped with at least one metal from the group comprising iron and/or noble metals.
A Raney-Copper catalyst wherein the initial alloy contains more than 50% Cu so that the finished catalyst contains more residual Al than normally found under the same activation conditions.
A Raney-Copper catalyst wherein the initial alloy is heat treated in air at temperatures higher than 500° C. before activation.
A Raney-Copper catalyst where the initial alloy has more than 50% Cu and is heat treated past 500° C. in air.
A process for the catalytic dehydrogenation of alcohols to their corresponding carbonyls and carboxylic acids, wherein a Raney-Copper catalyst according to claim 25 is used.
